🚨 BREAKING CHANGES #

Complete architectural rewrite with Map-based column management. All existing code must be updated.

What Changed

• Columns: List<BasicTableColumn> → Map<String, BasicTableColumn>
• Rows: List<BasicTableCell> → Map<String, BasicTableCell>
• Column identification: Index-based → ID-based
• Column ordering: List position → order field
• Callback: onColumnReorder(int, int) → onColumnReorder(String, int)

Migration Required

• Add id and order to all columns
• Convert row cells to Map structure
• Update callback signatures
• See Migration Guide for details

✨ What's New #

Performance 🚀

• 80% faster column reordering (no row data reorganization needed)
• 20% faster cell lookup (direct Map access)
• Sort states persist across column reordering

New Features

• Map-based architecture with ID-based column management
• Enhanced ColumnSortManager with ID-based operations
• Debug tools with column order visualization
• Data validation with integrity checking
• Helper methods for easier migration and data manipulation

New API Methods

• BasicTableColumn.reorderColumn() - Smart column reordering
• BasicTableColumn.normalizeOrders() - Fix order gaps
• BasicTableRow.getSortedCells() - Ordered cell rendering
• BasicTableRow.fillMissingColumns() - Handle missing cells
• onColumnSortById - ID-based sorting (recommended)

🐛 Fixes #

• Fixed sort state loss during column reordering
• Improved null safety for missing cells
• Enhanced error handling for invalid operations

Example Improvements #

• Added column visibility feature with FilterChip controls
• Improved code structure with separated components
• Enhanced UI and state management

Fixed #

• Resolved issues with column reordering, ensuring drag-and-drop functionality works correctly across all platforms.
• Fixed sorting bugs, improving the stability of ID-based sorting in ColumnSortManager to maintain correct sort states after column reordering.
• Enhanced robustness of column reordering and sorting logic to handle dynamic column changes seamlessly.

Added #

• Initial release of FlutterBasicTable package
• BasicTable widget with comprehensive table functionality
• Support for text, custom widgets, and status indicators in cells
• Column sorting (ascending/descending/none) and reordering
• Row selection with checkbox support
• Complete theming system for all table components
• Custom tooltip system with overflow detection
• Responsive column width calculation
• Row and cell interaction callbacks (tap, double-tap, right-click)
• Synchronized horizontal and vertical scrollbars
• Cross-platform support (Android, iOS, Web, Desktop)
